This is a funny question that I just had to take a stab at! :)
I do not think it is actually the yawn that makes the noise, but most people stretch when they yawn. This is known as pandiculation. This is just a guess but when you stretch it tightens the vocal chords similar to the strings on a guitar. The yawn itself takes in air quickly which strum the chords (hope you can follow a metaphor, cause I can't think of how else to explain it) and produce the noise you hear when you yawn. This is why breathing alone does not cause the noise because the vocal chords are not tightened. Like if you were to try and play a guitar with very loose strings, it would make no sound. This is just a theory, but it is the best explanation that I have. :)
When you yawn, the muscles in your inner ear, called the tensor tympani and stapedius, contract. This can affect the pressure in your middle ear, causing a temporary change in how you perceive sound. This is why your ears might feel like they "pop" or sound muffled during a yawn.
The typical written expression for a yawn sound is "ho hum."
The noise made during a yawn is due to the sudden intake of air expanding the eustachian tube in your middle ear, which can create a "popping" or "clicking" sound. This is a normal physiological response and is nothing to be concerned about.
The onomatopoeia for a yawn is often represented as "yawn" itself, capturing the sound of the action. Some might also use "ahhh" or "ahh" to convey the sound made when opening the mouth wide during a yawn. These representations evoke the essence of the yawn's sound and feeling.
Exactly how weird, and for how long? It is possible that you are unaware of something really odd or funny about your body movements or vocalizations when you yawn, and your daughter's weirdness is an attempt to stifle a reaction that she thinks might embarrass you. If that's the case, you have a chance to bond a little, have a laugh and a yawn or two, and maybe learn to yawn in a less, well, gaping manner? For some reason, your question really gives me a weird urge to see you yawn.
No but they make a noise that sounds like barking
The sound you hear in your head when you yawn is likely the stretching of the jaw muscles and surrounding tissues, not an actual sound. Yawning typically doesn't produce a physical sound within the head.
The word "yawn" has the same vowel sound as "lawn."
The spelling of the yawning sound is "yawn."
a weird noise
it makes a weird sound, thats all i have to say
Caw! That is if you mean the sound they make. They also have a weird sound for talking quietly to each other.
